Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique. We are able to provide you these solutions supported by life test data and years of excellent field performance.As your partner, we provide sealing solutions for centrifugal pumps,agitators and other rotating equipment, and help you consolidate your brand and market position.

Mechanical sealing adopts the principle of mechanical friction sealing, which has excellent sealing performance, which can effectively prevent leakage and protect the safety of the environment and equipment. Compared with traditional packing seals and rotary seals, the sealing effect of mechanical seals is more reliable.

Our products are made of high quality materials and manufacturing processes, with a long service life and low cost of use. It can effectively reduce the maintenance costs and operating costs of equipment .

Shanghai Queeny Mechanical Equipment Co.,Ltd.is an enterprise specializing in the R&D,manufacture and export of mechanical seal products,headquartered in Pudong New Area,Shanghai.Our products mainly include component seals,dry gas seals,metal bellows seals,mixer and agitator seals,single & dual cartridge seals,silicon carbide parts and tungsetn carbide parts,which can replace John Crane, Burg--mann, AES, Chesterton,Flowserve,Rotenand other similar products,they are widely used in water treatment,petroleum,chemical,food,medical and other industries.
